When your furnace is operating like it should, it should give warmth without making too much disruption. While it’s normal to catch your furnace making noise as it turns on, other sounds are showing your furnace should get immediate professional assistance.

Here are some of the most reported furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating specialists are here to fix the problem with the best furnace repair in Albuquerque, New Mexico.

1. Furnace Makes Banging or Knocking Sounds

You might have an urgent situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it can signal there could be a few problems. These range from gas accumulating in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s important to set seasonal furnace maintenance with I-Deal HVAC. One of the things our pros complete during this service is clean your furnace’s burners. When this component gets grubby, you could hear your furnace making a loud rumbling noise if ignition takes longer than normal. The following gas buildup may fracture your furnace’s heat exchanger, where natural gas turns into heat. Any cracks in it can emit carbon monoxide, which is normally released away from your home. This dangerous gas can be deadly in large concentrations.

If you’re aware of banging or knocking sounds coming from your furnace, I-Deal HVAC advises turning it off and calling us at 505-445-1250. Too much natural gas in your furnace or a ruptured heat exchanger are serious problems that require prompt repairs.

Banging Sounds Coming from Your Ductwork

Your furnace relies on ductwork to provide heated air around your house. If the ductwork wasn’t put in properly or is getting dated, it can be loud when your furnace is on. This might be the problem if your furnace makes a banging noise when it shuts off. Call I-Deal HVAC at 505-445-1250 and we’ll figure out the problem.

2. Furnace Buzzes Constantly

If you observe your furnace making a buzzing noise, don’t hesitate to call us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to run on the correct voltage. If wires or the box isn’t tight enough, you may hear a low humming noise in the furnace when off. Your furnace also has a blower motor, which sends heated or cooled air throughout your residence, and a capacitor, which turns on the motor. If either of these pieces are failing, they will buzz when the furnace starts.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be the result of something small, like a loose screw, or something major, like a broken part. In either case, we recommend shutting off your furnace and contacting our heating professionals at 505-445-1250 for support.

4. Furnace Making a Squealing Noise

If your furnace makes a high-pitched noise, like squealing, when it’s running, it’s making an effort to get your attention it could use some TLC. If you’ve forgotten furnace maintenance the last couple of years, belts could be worn down or a bearing might need to be lubed. We know that maintenance often slips your mind, but our pros can get your furnace heating quietly again fast.

5. Furnace Making a Whistling Noise

When you’re hearing your furnace making a whistling noise, it’s typically the result of an air leak in your ductwork. You might also be aware of whistling while the furnace is operating if a floor vent isn’t secure. If you’ve examined your vents but are still noticing whistling, I-Deal HVAC can assist you. It’s critical to get loose ductwork taken care of quickly, since it can create comfort issues in your house and increase your heating costs.

6. Furnace Makes Noise that Sounds Like Scraping Metal

It’s not a good sign if you detect your furnace making a grinding noise. This metal-on-metal racket frequently means there’s trouble with your furnace’s blower. Turn off your furnace off right away and call us at 505-445-1250 for assistance.
